Application June 21,

9 Claims.

This invention relates to certain new and useful improvements in cartonsfor radio tubes and the like, the object being to provide a carton withmeans for resiliently supporting a radio tube therein in such a mannerthat it can move longitudinally in order to project one end thereofoutwardly in order to test the tube and yet the tube is permanentlylocked within the carton so that it cannot be removed without destroyingthe carton, thereby preventing bootlegging of an inferior product andthe unauthorized packing of such product.

Another object of my invention is to provide a carton which is formedfrom a; single blank to provide a tubular casing having integral endclosures provided with self-locking tongues and integral partitions forsupporting the radio tube whereby the carton can be manufactured cheaply, the partitions being so constructed and connected to one wall of thecasing by flaps that resilient means is provided for supporting thetube, the partitions being adapted to be bowed ,in order to resilientlysupport the tube whereby the tube will have a tendency to return to itsoriginal position after the end has been forced outwardly to test thesame.

Another object of my invention is to provide a novel construction forlocln'ng the end closures after the tube has been placed in positionwithin the container without the use of glue or separable fasteningmeans, whereby the cost of manufacturing the container is greatlyreduced and a positive lock is provided for the end closures to preventthe tube from being removed without destroying the container.

Other and further objects andadvantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings,

Figure 1 is a perspective view of a container constructed in accordancewith my invention;

Figure 2 is a longitudinal section showing the radio tube in dottedlines in its normal position; Figure 3 is an enlarged longitudinalsection showing the radio tube extended in position to be tested;

Figure 4 is a section on line 4-8 of Figure 2; Figure 5 is a detailperspective view showing the locking tongue before it has been insertedwithin the slot of the wall of the container; Figure 6 is a detailperspective view showing the locking flaps of the tongue bent inposition to be forced through the slot in the wall of the containe and V1935, Serial No. 27,808

Figure '7 is a plan view of the blank from which the carton is formed.

In carrying out my invention, I form the complete carton from a singleblank of cardboard or other suitable material, which comprises a tubularcasing formed of side walls I, 2, 3 and 4, the wall 4 being providedwith a flap 5 which is adapted to be secured to the inner face of thewall l by any suitable adhesive material, the, flap being formedby ascore as shown in dotted lines. Formed integral with the wall 3 of thetubular container at each end are end closures 6 and 1 which are scoredas shown to provide side flaps 6' and I and locking tongues 8 and 9, thelocking tongues 8 and 9 being scored as shown by dotted lines to provideresilient looking ears 8' and 9, forming substantially T- shaped heads,these locking tongues and ears being adapted to be bent into theposition shown in Figure 6 and forced through slots l0 formed in thewall I of the tubular casing in order to lock the closures in closedposition as will be hereinafter more fully described.

The end closures 6 and I are provided with opening 6 and 1 opening 6being for the purpose of allowing a finger or thumb to be inserted inorder to force, as for example, a radio tube ll outwardly through theopening 1 in order to allow it to be tested as clearly shown in Figure3.

Formed integral with the ends of the wall I of the tubular container aretube supporting members 12 and [3 which are scored on the dotted linesto produce partitions l4 and I5, connecting flaps l6, and I9.

The tubular container formed by the side walls I, 2, 3 and 4 ispreferably rectangular in shape and can be formed of any suitablematerial, such as pasteboard and the like. After the flap 5 has beencemented to the wall I, the tube supportling members l2 and I3 areforced inwardly through the open ends of the tubular container into theposition shown in Figure 2 and the size of the partitions I4 and I5 issuch that they are bowed as clearly shown, it, of course, beingunderstood that the radio tube II is placed in position within thecarton within the partition 15 before the partition I4 is forced intoposition. When the partition [4 is forced into position, the end of thetube extends into the opening l, the other end of the tube being seatedin the opening I5 of the partition l5 and as both of i1 and I1 and guideflaps l8 these partitions are of a greater size than the inner size ofthe container, they bow when port the tube H whereby when the tube is inits normal position as shown in Figure 2 andis forced outwardly to testthe'same into the position shown in Figure 3, the partition bends sothat the bow is in the opposite direction and as the cardboard isflexible, it has the tendency to return to its original position whenpressure is removed'from the same so as to return the radio tube intoits normal position. 10-

The connecting flaps i6, i6, H and H of the partitions id and i assumethe position shown in Figures 2 and 3 when forced into position withinthe container in order to provide pockets 2d and 26 to protect thelocking tongues 8 and 9 when in locked position, whereby it isimpossible to insert an instrument of any kind into the carton andmanipulate the ears 8 and d of the locking tongues t and 9 in, order torelease the same and to allow the closure members to be opened whereby apositive lock is provided which, when once inserted into lockedposition, closes the ends of the carton and permanently locks the radiotube therein so that it is impossible to remove the same withoutdestroying the carton.

Assuming that the radio tube has been placed in position within thecarton within the resilient supporting means, the ears $3 of the lockingtongue 8, as for example, are bent back upon the tongue into theposition shown in Figure 6 and forced through one of the openings it andas the material from which the tongue is formed is flexible, the ears ofthe tongues spread outwardly after passing through the opening so as topositively and permanently lock the closure in closed position. It is,'of course, understood that the opposite end closure is secured in alike manner and the radio tube will now be packed in a carton so as tothoroughly protect the same in shipment and yet allow the same to movetherein so that one end can be projected outwardly in order to test thesame and as the partitions are flexible, it not only resiliently sup-'ports the radio tube, but has the tendency to return the tube to itsnormal position within the container after being forced outwardly totest the same. I

While in the drawings and specification I have shown and described acarbon especially designed for the merchandising of radio tubes, it is,of course, understood that the same can be used for merchandisingelectric light bulbs or any other objects which are generally tested todetermine their condition prior to sale.

From the foregoing description it will be seen that I have providedacarton with resilient partitions resiliently supported within thecontainer for supporting a radio tube resiliently to enable one end ofthe tube to be forced out of thecontainer in order to allow the same tobe tested and when released, will return to its normal position by theresiliency of the supporting means and partition.
